Influence of sowing date on wheat phenology and grain yield – Wagga Wagga 2017 locations
Aims

To investigate the influence of sowing date on the phenology and grain yield responses of a core set of 36 wheat genotypes.
 

Key messages

• Frost significantly influenced flowering date and grain yield in 2017.

• High grain yields can be achieved from a range of genotype × sowing date combinations.

• Whilst flowering time is important in maximising grain yield potential, timing pre-flowering phases was also found to significantly influence grain yield.
